Steering and manoeuvering system for water-borne vessels with two individually turnable propulsion units aranged mutually spaced athwartships in the stern portion of the vessel, and including an actuating turning device (7,8) actuable by a steering control (1), e.g. a lever, such as to maintain the propulsing units parallel during turning in normal sailing of the vehicle ahead or astern, i.e. in the so-called normal steering mode, and an actuating drive device (9,10) for setting the propulsive power and direction ahead/astern of the respective propulsion unit, said drive device being actuable by a power control (2). The system is switchable between said normal steering mode (3) and at least one special manoeuvering mode (4,5), in which the two propulsion units achieve a force resultant directed substantially athwartships for athwartships and/or turning movement of the vessel.

Steering and manoeuvering system for water-born vessels with two individually turnable propulsion units arranged at the stern portion of the vessel and mutually spaced athwartships, including an actuating turning device for controlling the turning angles of the two propulsion units such that they remain mutually parallel in a normal steering mode of the vessel, wherein the vessel is moving ahead or astern, said turning device being actuable by a steering control, and an actuating drive device for setting the propulsive power and direction ahead/astern of the respective propulsion unit, said drive device being actuable by a power control, characterized in that the steering and manoeuvering system includes a function selector with the aid of which the system is switchable between said normal steering mode, and at least one special manoeuvering mode, where the steering control is disconnected from its normal steering function where the propulsion units are kept parallel, and said actuating turning device is instead actuated automatically irrespective of the position of the steering control for setting the two propulsion units at symmetrical turning angles in opposite directions so that the two propulsion units achieve a force resultant directed substantially athwartships, while said actuating drive device is actuated for setting the two propulsion units in opposing propulsive directions ahead/astern; and in that the steering control, in said at least one manoeuvering mode, actuates said actuating turning device such that the turning angles are changed symmetrically in opposite directions, whereby the point of action of the force resultant is displaced along the vessel\s fore and aft line, including the linear extensions thereof.
